When I got my Kindle (1) last year, I downloaded the Kindle User's Guide, changed the filename from 13408_1.azw to 13408_1.mobi and opened it up in Mobipocket Reader. I found it a lot easier to experiment with the Kindle when I had the manual open on my laptop instead of trying to read it on the Kindle while pushing buttons.
